n8n before 1.123.73 Credential Exposure via Error Logging

Impact

n8n versions before 1.123.73, 2.35.4, and 2.36.2 have a credential exposure vulnerability in certain nodes, allowing authenticated users to read plaintext secrets via the REST API. The vulnerability is due to decrypted credentials being sent outside error handling. Affected versions include those less than 1.123.73, 2.35.4, and 2.36.2.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

n8n before 1.123.73, 2.35.4, and 2.36.2 contains a credential exposure vulnerability in the Strapi, SeaTable, and Mailcheck nodes. These nodes send their decrypted credentials to the authentication endpoint via the raw legacy HTTP helper outside any error handling, causing the plaintext secret to be persisted in execution error data. Any authenticated user can read the plaintext secret from their own execution through the REST API, bypassing the blank-value redaction enforced by the credentials API.
